Method and system for performing a logical loopback test

Abstract

Systems and methods for obtaining logical layer information in a frame relay and / or asynchronous transfer mode (ATM) network are described. In an exemplary embodiment, a physical layer test system, such as an integrated testing and analysis system, communicates with a broadband network management system, which in turn communicates with an element management system for a frame relay and / or ATM network.

Benefits of technology

[0010]The present invention allows for remote testing for logical layer information by placing an INTAS, a BNMS, and an EMS in communication in series. The present invention allows users or analysts to obtain logical layer information remotely using a physical layer test system, whereas previously obtaining logical layer information required human personnel physically testing each individual circuit using a logical test box connected to the circuit itself or a DCS providing physical access to multiple circuits. Methods and systems of the present invention allow for the use of a single logical test box connected to the frame relay and / or ATM network in each LATA. Accordingly, for example, rather than needing 25–30 boxes for the Atlanta LATA, only a single logical test box is needed, greatly reducing both the equipment and personnel costs associated with obtaining logical layer information.

Problems solved by technology

As the number of customer and network installations has increased, so has the difficulty of effectively and efficiently monitoring and managing the networks supporting the providers' customers.

However, in creating and testing a loop between points A and B, there is no way to determine what is occurring at the logical layer.

Thus, if the network problem is in the logical portion of the frame relay or ATM network, physical layer testing cannot determine where the problem lies.

Presently, no cost effective remote logical layer testing solutions exist.
